Abstract
A push-pull rotary switch includes a board having two circuits on opposite sides. Conductors are respectively positioned above the circuits for contacting ground and contact pads of the circuits. A shaft extends through the conductors and the board and is rotatable and moveable between inward and outward positions. The conductors are connected to the shaft to rotate and move with the shaft. A first conductor contacts the ground pad and a contact pad of a first circuit when the shaft is in the inward position. A second conductor contacts the ground pad and a contact pad of a second circuit when the shaft is in the outward position. A first trace is connected to the first circuit ground pad and a second trace is connected to the second circuit ground pad. A contactor connects a ground trace to at least one of the first and second traces at all times.
